Email Verification
Overview
Email verification confirms that an email address exists, can receive messages, and is controlled by the applicant. Basic methods use OTP links/codes and suppression of disposable or risky domains. Advanced checks are enriched with domain age, MX/SPF/DMARC status, breach exposure, and behavioral patterns (velocity, device/IP reuse).In onboarding and authentication, verified email improves recovery flows, reduces fake signups, and adds a possession factor though it is weaker than phishing-resistant methods. Compliance programs log consent, minimize PII, and respect unsubscribe and localization rules. Email risk signals should feed fraud scores, trigger step-up authentication, and coordinate with phone and device intelligence. Done well, email verification reduces support load, false positives, and account takeover pathways..
